Overview

The MPC8309 incorporates the e300c3 (MPC603e-based) core built on Power Architecture® technology, which includes 16 KB of each L1 instruction and data caches, dual integer units, and on-chip memory management units (MMUs). The MPC8309 also includes a 32-bit PCI controller, two DMA engines and a 16/32-bit DDR2 memory controller with 8-bit ECC.

A new communications complex based on QUICC Engine technology forms the heart of the networking capability of the MPC8309. The QUICC Engine block contains several peripheral controllers and a 32-bit RISC controller. Protocol support is provided by the main workhorses of the device—the unified communication controllers (UCCs). A block diagram of the MPC8309 is shown in the following figure.

Each of the five UCCs can support a variety of communication protocols such as 10/100 Mbps MII/RMII Ethernet, HDLC and TDM.

In summary, the MPC8309 provides users with a highly integrated, fully programmable communications processor. This helps to ensure that a low-cost system solution can be quickly developed and offers flexibility to accommodate new standards and evolving system requirements.
